Rayson PrimeBond · Primers & bonding coats
Rayson PrimeBond W10 is a one-component, water-based acrylic primer, sealer and bonding agent for smooth concrete and mineral substrates, applied ahead of Rayson UraForce water-based topcoats.
PrimeBond W10 is the low-odour entry point to Rayson floor systems. Supplied ready to use in a single pack, it needs no weighing or ratio mixing — stir for two minutes and apply by brush or roller. It seals smooth concrete and mineral substrates and provides the bond for Rayson water-based urethane topcoats.

| Surface preparation | New concrete should be at least 28 days old with moisture content below 5%. Remove laitance and loose material; mechanically prepare damaged concrete to expose aggregate. On existing concrete, prefer mechanical preparation followed by industrial vacuuming; degrease oil and grease. The substrate is sufficiently dry when surface relative humidity is 75% or lower. |
|---|---|
| Mixing / dilution | One pre-weighed component; stir well for 2 minutes with a mixing paddle before use |
| Application method | Short-bristled brush, Roller |
| Coverage | 5–10 m² per litre depending on substrate condition |
| Application conditions | Minimum substrate temperature 5 °C; minimum mixing temperature 10 °C; minimum curing temperature 5 °C; keep floor dew point within 3 °C of atmospheric temperature. |
| Drying & curing | Surface dry approximately 1 hour at 28 °C |
| Recoat interval | Available from the Rayson technical team on request. |
| Film / thickness | Penetrating primer; consumption governs film. |
| Pack sizes | 20 L plastic pail |
| Storage | Store under cover in dry conditions, protected from temperature extremes. |
| Shelf life | Approximately 12 months unopened, subject to storage conditions. |
